Weather conditions: |
| In the mountains, the depth of snow and dates of spring snow melt were similar to average long-term values. The highest water level in the rivers was either average or lower than usual. Summer was warm, in the eastern parts of this area it was very dry until 13 August, however rains, snowfall and strong winds occurred there later.

Breeding conditions:
|
| Arctic Foxes were rather scarce in northern parts; Long-tailed Skuas commonly bred in montane areas; breeding success of Rough-legged Buzzard was higher than in 1992. Few Snowy Owls were thought to breed at the seacoast. The numbers of Willow Grouse Lagopus lagopus and Rock Ptarmigan L. mutus were low. Large quantities of berries ripened in the central parts of the study area. The number and breeding success of most wader species was similar to average estimates. It is probable that reproduction was less successful for those waders breeding in the mountains south of the northern tree-line of larch (Whimbrel, Common Sandpiper Actitis hypoleucos, Terek Sandpiper and Grey-tailed Tattler Heteroscelus brevipes).

Rodent dynamics:
|
| The number of small rodents was greater than in 1992, although still did not reach maximal level.
